た。2. Description of the Related Art Conventionally, methods for percutaneously detecting information inside the body from outside the body include a method using a stethoscope and a method using a sphygmomanometer, and in recent years, an X-ray TV, an ultrasonic image diagnostic apparatus, etc. There is a method of detecting the shape of an organ by the method, a method of detecting bioelectromotive force by an electrocardiograph, an electroencephalograph, a method of detecting blood flow by an ultrasonic Doppler blood flow meter, and the like. However, the information inside the body obtained by these methods is obtained by receiving signals such as electromotive force and sound waves generated inside the body, and by receiving signals such as X-rays and ultrasonic waves given from the outside to the body. However, there is a drawback in that information that is not generated in the body, particularly information that does not generate a signal in the body regarding body fluid, cannot be obtained. For example, when coronary artery bypass surgery is performed to treat coronary stenosis of the heart, since the patient is originally prone to coronary artery stenosis, the bypass blood vessel (particularly venous bypass) also causes stenosis. Therefore, it is necessary to continue to monitor the stenosis state of the coronary artery of the surgical patient even after the surgery. However, conventionally, in order to detect the flow rate and flow velocity of the coronary artery, it is necessary to insert a sensor into the coronary artery by surgery every time it is measured, and an angiography method is required to examine the degree of stenosis. It could not be easily detected by skin.
